Informativeness of laboratory methods of research of pregnant women with chronic inflammatory bowel disease

Abstract

Annotation. The aim of the work is to demonstrate the importance of laboratory parameters in pregnant with chronic inflammatory bowel disease. The examined patients were divided into the main group (ulcerative colitis, n=40) and the control group (practically healthy women, n=30). The formation of observation groups was carried out by methods of continuous and selective analysis. The indicators of vasculo-endothelial growth factor (VEGF), serum levels of vitamin D, homocysteine, markers of neutrophilic intestinal inflammation (serum levels of tumor necrosis factor α and interleukin-4 were studied). Database formation and all calculations were performed using the software packages STATISTICA6.1 (№АХХR910F374605FA) and MedCalc (version 17.7.7, MedCalcSoftware). Statistical processing of quantitative data included the calculation of the mean and standard error of the mean (± m) using parametric criteria (in the case of a normal distribution law) or a nonparametric Mann-Whitney test (if the distribution law differs from the normal one). In the analysis of the informativeness of laboratory methods, it was found that women with chronic inflammatory bowel disease were characterized by: increased levels of fecal calprotectin, proinflammatory cytokines TNFα and interleukin-4, homocysteine. The analysis of markers of endothelial dysfunction in pregnant women with COPD was diagnosed with a significant increase in serum levels of vasculo-endothelial growth factor and an increase in microalbuminuria, which allowed to talk about the association of ulcerative colitis with the development of gestational endotheliopathy in such women.
